Abstract

This study examined the effects of simulator sickness (SS) as a function of the visual complexity of animated virtual actors (AVAs) and the virtual environment (VE) in a virtual scene. Visually complex stimuli may be attractive; however, studies on SS indicate the possibility of significant health risks outweighing the expected benefit in virtual reality (VR) simulations. This study used a series of simulations to teach the basic skills required for village fire fighting to manage fires caused by car accidents. The participants learnt in one of 4 experimental conditions; simple (simple AVAs and simple VE), simple world (lifelike AVAs and simple VE), simple AVAs (simple AVAs and lifelike VE) and lifelike (lifelike AVAs and lifelike VE). We predicted that: (1) SS ratings would increase with the scenes' visual complexity and (2) simpler VEs would compensate for the effects of visually complex AVAs. Surprisingly, the results contradicted our predictions, with no effect of either variable. We discuss possible explanations for these results, and suggest future research directions to design safe VR simulations.
